Outline

This project tries to build an autonomous knowledgebase building system for dialogue system to realize an intelligent cooperative interaction between humans and machines. We build an agent system that analyzes language structures in user utterances focused on relationships between predicates and their arguments. The system automatically learns and updates the knowledgebase that the system has inside by using the analyzed results. The system also learns the policy, mapping between the observation and the system action, to balance the user demand for the task and the system demand for knowledge acquisition to realize an intelligent cooperation with users.
